Are you new to Online Blackjack? Want to refresh your knowledge, or maybe you're interested in the differences between online and offline play? Then take a seat and discover everything you need to know about playing blackjack online.


Let's start with the basic rules and a description of how blackjack works in practice. If you plan on playing online blackjack for real money, make sure you have an account with a cash balance. You can create your UK account by clicking here.

Once you're logged in and your account is funded, choose your Online Blackjack game variation, and then select one of the table limit options. Be sure to choose limits that you are comfortable with. You can also leave the table at any time and select new limits that suit your style.

Card Values

Cards in Online Blackjack are worth their face value and all picture cards are worth 10. The only exception is the Ace card, which can be worth 1 or 11.

So, a 4 card is worth 4 points, and a Queen card is worth 10 points. If this is your Blackjack hand, then you currently have 14 points in total.

Making a Bet

To stake your first bet, choose your chip size and place it on the table. You can place multiple chips to increase your bet. For example, setting 2 x £0.50 chips means your total bet will be £1.

Single-Hand & Multi-Hand

Some tables are single-hand, which allows you to play with one hand of cards. Multi-hand tables will enable you to sit at multiple seats and play more than one hand at once.

Order of Play

Once you've placed your first bet and clicked or pressed DEAL, the game will begin.

  1. You'll be dealt two cards face up, and the Dealer will be dealt two cards – one face up and one face down. (Pay close attention to the dealer’s face-up card, as it will help with your next decision).
  2. Now decide if you want to Stand, Hit, Split, Double Down, or Surrender.
  3. The Dealer will take his turn last. He will Hit when the value of his hand is worth 16 or less and Stand when his cards are worth from 17 to 21.
  4. You will win when:

a. The total of your hand is higher than the dealers, but less than 21 or equal to 21.
b. Or if the dealer busts (holds more than 21) and you did not go over 21.
c. Blackjack – if your starting hand contains an Ace and a 10-value card, congratulations you've got a Blackjack and have won the round with a higher payout of 3:2. But be careful, the Dealer can also deal a Blackjack to himself.

Card Values

Cards in Online Blackjack are worth their face value and all picture cards are worth 10. The only exception is the Ace card, which can be worth 1 or 11.

So, a 4 card is worth 4 points, and a Queen card is worth 10 points. If this is your Blackjack hand, then you currently have 14 points in total.


If your total hand is over 21 points, then you'll automatically Bust, and the round will be over but don't worry, you can't go Bust on the very first deal. Only if you decide to Hit (accept an extra card) can you go Bust.

Hit or Stand

  • Hit - After you have received your two cards from the Dealer, you can decide if you want to take another card – you can do so by pushing the Hit button.
  • Stand - If you want to keep only your current hand, press Stand to end your turn.

Advanced Options

You can do more than just Hit or Stand in Online Blackjack. If you want to master the game and reduce the house edge to its lowest, you'll need to learn all the advanced options as well.

  • Split

    If you're dealt a matching pair of cards, such as 2 x 5s or 2 x 10s, you can split them. Which means that you'll automatically make another matching bet, your cards will split apart into two separate hands and you'll receive another card with each hand.
  • Double Down

    If you think by drawing one more card, you'll be in a strong position, then you can use the Double Down. It will double your bet, and you'll receive one more card which will then end your turn.
  • Surrender

    Use the Surrender to forfeit your turn and receive half of your bet back. Sometimes it can be used after Splitting, depending on the blackjack variation you are playing.
  • Insurance

    If the Dealer has an Ace card showing, you'll have the option to take Insurance. By choosing this option, you'll win if the Dealer's 2nd card is a 10. It pays 2:1.
  • Side Bets

    Side bets allow you to place more wagers for the chance to gain extra wins even if your Blackjack hand doesn't beat the Dealer.
  • 21+ 3

    Betting on the 21+3 side bet allows you to try and make a three-card poker hand by using your first two dealt cards and dealers face-up card.
  • Perfect Pair

    To bet on a Perfect Pair, place your bet on the Player's Pair betting area just beneath each Blackjack hand's individual betting spot. You can also bet on the Dealer's Pair.
    • A Perfect Pair is when the first two cards dealt have the same number and suit, e.g. 2 x 6 of Diamonds.
    • Coloured Pair is when the first two cards are matching their colour and number, such as a 5 of Clubs and 5 of Spades. Both cards are black.
    • Red/Black Pair is when the first two cards have matching numbers, one is suited Red, and one is suited, Black.
Hand Pays
Winning Hand 1:1
Insurance 2:1
Blackjack 3:2
Perfect Pair 25:1
Coloured Pair 12:1
Red/Black Pair 6:1
Suited Three of a Kind 100:1

Basic Strategies and Tips

We mentioned how to use Split, Double and Surrender, but now let's talk about the optimal situation to use each option.

Split - You don't want to Split your cards recklessly in the hopes it will increase your odds, because it won't. Be sure to use the table below to get the best chances to beat the Dealer,based on the visible card in his hand. If you want to keep things simple, just remember that you should always split a pair of 8’s or Aces, regardless of what card the dealer is showing.

Your Hand When to Split vs the Dealer
2's, 3's 4 through 7
4's, 5's, 10's Never
6's 3 through 6
7's 2 through 7
8's Always
9's 2 through 6 and 8 or 9
Ace's Always

Double Down - Double your bet in return for just one card. As you'll see in the tables below, when to double down is heavily dependent if you have an Ace in your hand.

Your Hand Double if Dealers face-up card is:
9 3 to 6
10 2 to 9
11 2 to 10

Your Hand Double if Dealers face-up card is:
A and 2 5, 6
A and 3 5, 6
A and 4,5 4,5,6
A and 6 3 to 6
A and 7 2 to 6
A and 8 6

Surrender - When should you forfeit your hand and receive half your original stake back? It heavily depends on the number of decks used and other factors. Most typically players surrender when the Dealer is showing an Ace card face-up, which means he may have a Blackjack hand.

  • How to win at Blackjack? You need to have a higher-scoring hand than the Dealer without going over 21. If it's a tie, then you'll receive your bet back. However, a Blackjack Hand will beat a regular 21-point hand.
  • Is it possible to count cards in Online Blackjack? The short answer is no. That's because the cards are shuffled after every round in Online Blackjack. In land-based casinos, the deck is shuffled after several hands have been played. Some gamblers believe they can gain an advantage by keeping a score of the number of high cards drawn, but such tactics are not possible in the online version.
